BindStateMachine

Struct BindStateMachine 

Source
pub struct BindStateMachine { /* private fields */ }
Expand description

State machine for binding a portal (Parse + Bind, no Execute/Sync).

Used by exec_iter to create a portal that can be executed multiple times.

Implementations§

Source§

impl BindStateMachine

Source

pub fn bind_prepared<P: ToParams>( buffer_set: &mut BufferSet, statement_name: &str, param_oids: &[Oid], params: &P, ) -> Result<Self>

Bind a prepared statement to an unnamed portal.

Writes Bind + Flush to buffer_set.write_buffer.

Uses the server-provided parameter OIDs to encode parameters.

Source

pub fn bind_sql<P: ToParams>( buffer_set: &mut BufferSet, sql: &str, params: &P, ) -> Result<Self>

Parse raw SQL and bind to an unnamed portal.

Writes Parse + Bind + Flush to buffer_set.write_buffer.

Uses the natural OIDs from the parameters to inform the server about parameter types.

Source

pub fn step(&mut self, buffer_set: &mut BufferSet) -> Result<Action>

Process input and return the next action.
